java.lang.NoClassDefFoundError Could not initialize class org.springframework.mock.web.MockServletContext

Question

We are using Spring-test-4.0.6 jar in test scope in our project. Under same project we also have javaee-6.0 dependency in provided scope.

I am getting this error in test case

Could not initialize class org.springframework.mock.web.MockServletContext at com.sample.TestWebDOMConfiguratorMultiple.setUp(TestWebDOMConfiguratorMultiple.java:77 )

Surprisingly replacing Javaee-6. 0 dependency with servlet-api-3.0.1 resolves this issue.

Note: Spring-4.0.6 pom has compile time optional dependency on servlet-api-3.0.1 .

Question is why is it working with servlet-3.0.1 and not with javaee 6.0 as we are trying to replace servlet-api-3.0.1 with javaee-6.0 .

Thanks in advance.

Answer 1

Without knowing the exact artifact that you are referring to as javaee-6.0 and without being able to see the full stack trace, it appears that your javaee-6.0 dependency contains Servlet API 3.0; whereas, spring-test-4.0.6.RELEASE explicitly requires Servlet API 3.0.1.

So that is likely the source of your problem.
